TheLingqu (traditional Chinese:靈渠;simplified Chinese:灵渠;pinyin:Líng Qú) is a canal inXing'an County, nearGuilin, in the northwestern corner ofGuangxi, China.
It connects theXiang River (which flows north into theYangtze) with theLi River (which flows south into theGui River andXijiang), and thus is part of a historical waterway between the Yangtze and thePearl River Delta. It was the first canal in the world to connect two river valleys and enabled boats to travel 2,000 kilometers (1,200 mi) overland between Northern China and thePearl River Delta.[1] It is also one of the most well-preserved such projects in the world.[2]
The canal is 36.4 kilometers (22.6 mi) long.[3]
In 214 BC,Qin Shi Huang, the First Emperor of theQin dynasty (221–206 BC), ordered the construction of a canal connecting the Xiang and the Li rivers, in order toattack theBaiyue tribes in the south. The architect who designed the canal was Shi Lu (Chinese:史祿). It is the oldestcontour canal in the world,[1] receiving its water from the Xiang. It was fitted with thirty-sevenflash locks by 825 AD. There is a clear description of pound locks in the twelfth century, which were probably installed one or two centuries before.[4] The canal also aidedwater conservation by diverting up to a third of the flow of the Xiang to the Li.[3]
The canal has been placed on theUNESCOWorld Heritage Sites tentative list.[3]
